BOILER-FLUE CLEANER.

The Schedule referred to in thesev Lettera Patent and 4making part -of the same.

To all whom it may concern Be it known that I, JOHN FAIRcLoUen, ot' St. Joseph, in thecounty of Buchanan, and State of Missouri, have invented a new and improved Flue-01eaner; and I do hereby declare that the following is a full, clear, and exact description thereof, 4which will enable others skilled in the art to make and use lche same, reference being had to the accompanyingdrawings, forming part ot? this speciticatkpn.l

Theobject of my invention is to provide an improved device for cleaning boiler-dues by means of steam.

v The device consists ot' a metallic pipe, so jointed to the dome of the boiler, and composed of sections, so jointed to each other that it may be folded back upon the boiler out of the way, and also so that* the vdis-V charge-'end or nozzle may be placed at any desired angie to lthe mouths or ends lof the fines.

Heretofore bthe pipes connected' with boilers for a similar purpose, have been rigidly attached to the same, so as to prevent their folding back, so as to be out ofthe way of the engineer, and their nozzles have been likewise so jointed, and the whole arrangement such as to preclude the possibility of the steam being discharged at all angles into the ues. Thus the ends or mouths of the upper and lower range ol' dues cannot be perfectly,'if at all cleaned.

The drawing representsa side elevation of a boiler with apart of the shell broken away, showing the 1nteiior tubes, and providedwith my improved arrangement of tubes.V

A is the boiler.

B, the steam-domafrom Whicha rigid joint of tube projects toward the side of thev boiler, provided with a stop-cock, C, and having a joint oi' tube, D, connected toit at E, so as to oscillate on it in a vertical plane.

This joint reaches beyond the end of the boiler, and has similarly jointed to -it another joint, F, also oscil# lating in a vertical plane, but -at right angles to the plane of oscillation of the tube D.

To this tube F is connected, by double joints H l, a long section, K, having a nozzle, L, jointed to it at M, and arranged to be held at'the ends of' the lines, for discharging the steam into them.

This arrangement admits of' moving the said nozzle around in acircle, corresponding with the tubular forms oi' the said lues, so as to discharge the steam over the whole'of the surface o.' the tubes in' a Way to clean ofi` and'scour 'the interior ofthe dues very effectively.

Having thus described my invention,

What I claim as new, and desire tosecure by Letters Patent, is-

The metallic pipes D F K, and nozzle L, so jointed together,.and to the do'me B of the boiler, that they may be conipactly folded back upon the latter, out of the way, and so that the steam may be discharged into the endsv of the dues at any desired angle, as specified. i

The above speciiicatiou of my invention signed by me, this 12th day of August, 1869.
